Have Pilot Bearing leak, causing oil in clutch
Hi,
I have a 402 LS2, and the pilot bearing is leaking inside the clutch... ordered new parts to work on the clutch side, but I can't find the part # for the pilot bearing as well as the 1" plug that goes behind it.
What are those 2 items part # ?
Thanks,

rear main seal is perfect... oil is coming from the middle of the crank.
fwiw, It's an EAGLE crank... and from what I read, it's fairly common.
I can post pix later.

i'll post some pix... the oil is literally coming from the center, where the pilot bearing is.
once i get home late tonight, I'll show you a few pix... so you can see... I triple checked the rear-main seal, and it's clean as hell... no evidence of any oil coming from there... as for the flywheel bolts, clean... but the pilot bearing, you can see the oil wanting to just come out of there.

Guys, it's coming from the center of the crank...we've seen it on numerous aftermarket crankshafts! The pilot bearing is a 14061685 from GM..
Maybe 873008 for the seal/bearing from Eagle? That's an old part number that was stored in our system...so it might not be accurate these days.

Its physically impossible for engine oil to come out of the flywheel bolt holes. Their machined into the crank. Thats equivelant to brake fluid coming out of your wheel studs..
When you pull the pilot bearing, there is a pressed in plug that goes into the back side of the crank (behind the pilot bearing). If its not seated properly, or has been hit when you were removing an old pilot bearing, it can damage it and cause it to leak.
Its a PITA to replace, but needs to be done right.
So just buy the plug, and new pilot bearing, and you'll be good to go..

You can pick up a 1 inch freeze plug from most Auto part stores.The old freeze plug is easy to remove.Make sure you do not drive the new plug to deep into the center of the crank.It only needs to go just past the pilot bearing.

Thanks, the GM part # has the same inside diameter, but it's not the same bearing... won't fit.
As for the part # from Eagle you weren't sure, you were actually dead on.
It's a Pioneer 873008 bearing.
Eagle is sending me one.

The GM freeze plug was a tighter fit than a 1" freeze plug from a parts store (like AutoZone). When I tweaked my GM plug I had to get a new GM one (about 4 bucks for a stupid little plug).

It is not a problem with all aftermarket cranks, it only happens on the Eagle products.
You should run some type of sealer on the flywheel bolts or they can seep oil also as they are drilled threw the rear flange into the engine crankase on stock as well as aftermarket cranks.

As Kurt said, crank flange holes are not blind, they are open to the crankcase.

was a real PITA to remove the pilot bearing + freeze plug... managed to get them out and clean properly.
ruined freeze plug #1 during installation... #2 went perfect.
sealed it well too.
bearing is in... thanks to EAGLE customer service... really good and fast.
flywheel is installed + clutch w/ new friction plates too... ready to put things back together.
